Theravance may yield to Glaxo

Theravance rose the most in 11 months on investor speculation that GlaxoSmithKline may purchase the 73 percent of the company that it doesn't already own.

Theravance gained 16 percent to $24.29 Monday, its biggest climb since April 2. Glaxo, the United Kingdom's largest drugmaker, may consider acquiring Theravance to fully control respiratory drugs the companies developed together, Piper Jaffray analysts said in a note to clients Monday.

Glaxo owns 27 percent of Theravance and may pay $51 a share for the rest of the South San Francisco drugmaker, Piper Jaffray said. That would be more than double the March 1 closing price and would value the remaining stake at about $3.6 billion.

Glaxo and Theravance formed an alliance a decade ago to develop respiratory drugs to help succeed Advair, Glaxo's aging best-seller. A Food and Drug Administration advisory committee will review the companies' Breo drug Thursday.

Tesla postpones annual report

Tesla Motors, the maker of electric vehicles led by billionaire Elon Musk, said it's delaying the company's annual report after finding an error related to accounting for capital expenditures.

The error will have "no impact" on previously reported cash, income statements, balance sheets or free cash flows, the Palo Alto company said Monday in a regulatory filing. Some unpaid capital expenditures from 2011 and 2012 may be reclassified as operating activities rather than investing activities, according to the filing.

Tesla is looking to become profitable this quarter, excluding some costs, as it increases production of the Model S sedan by least 25 percent. The electric-car maker is scheduled to bring out the Model X crossover in 2014.

Samsung seeks bigger victory

Samsung Electronics said it will seek a further review of patent damages awarded to Apple even after winning a reduction of about 45 percent of the $1.05 billion amount.

U.S. District Judge Lucy Koh in San Jose cut the damages award last week after finding that the jury based its decision on an incorrect legal theory.

Samsung and Apple have each scored victories in patent disputes fought over four continents since the iPad maker accused Asia's biggest electronics producer in April 2011 of "slavishly copying" its devices. The companies continue to battle over patents as they seek dominance of a mobile-device market estimated by researcher Yankee Group at $346 billion in 2012, even as Apple remains one of Samsung's biggest customers.

Trulia declines amid share sale

Trulia, the San Francisco residential-property listings website, fell in late trading after announcing plans to sell an additional $100 million in shares.

The company will use the proceeds to acquire or invest in businesses or technologies that complement its own, Trulia said in a statement Monday. Shares fell to as low as $26.20 in extended trading Monday.

The stock declined on concern that the sale will dilute the stakes of existing holders. Trulia shares had surged to a record last month amid optimism that gains in U.S. home prices would help boost advertising sales. The company competes with larger rival Zillow for listings and revenue from advertisers seeking to reach home buyers and renters.
